My first open-source library, a Rust implementation of Alexandre François' Resonate algorithm.
- real-time spectral analysis (think STFT/CQT)
- arbitrary frequency bins & per-bin time/frequency tradeoff
- no windowing or buffering
- Python & WASM bindings
- live mic browser demo

Hands-free Jevving on the Apple Watch!

Inspired by @kunalabcdani's coffee ordering demo, I had to see if I could get something similar working on my watch with "raise to talk" UX.

Built with @typesafeai Jev, @DeepgramAI Flux, and my new Rust crate, system2.

What if we could manipulate UI at the speed of thought?

Built this voice coffee ordering system with @typesafeai Jev. The drink and any updates show up while I’m still mid-sentence, ~200 ms from word to screen.

Feels pretty magical!

Thought I was already living in the future coding with Claude/Codex/GitHub/Termius on my iPhone/iPad.

Then I tried @theo's @t3dotcodes — and wow. Haven't been this impressed in a new dev tool in a long time. Superior UI/UX in almost every dimension. Highly recommend.
